FRUIT-JAR.

eeaesi.

To all whom it may concern:

Be it known that I, HENRY. B. BURNS, a citizen of the United States,residing at Fond du Lac, in the county of Fond du Lac and State ofWVisconsin, have invented a F ruit-J ar, of which the following is afull. and complete specification.

This invention is an improvement in fruitjars, and relates moreespecially to that class which is commonly known as the Mason type offruit-jar.

The primary object of my invention is to provide a fruit-jar of thischaracter with a closure of cheap construction which will hermeticallyseal the jar in such manner that the upper part of the contents of saidjar may be seen through the closure, and the condition of such closurewill indicate the condition of the contents.

A further object of the invention is to provide a closure for fruit-jarsin which the screw cap may be conveniently turned and will yieldinglyengage the threads of the neck of the jar so as to more firmly bind uponthe sealing-disk and gasket.

Other objects and advantages of the invention will hereinafter appear,and what I claim as new and desire to protect by Letters-Patent is morespecifically set forth in the appended claims.

In the accompanying drawings, which form a part of this specification:Figure 1 is a side view of the upper part of a fruitjar embodying myinvention. Fig. 2 is a sectional view through the closure and upperportion of the jar. Fig. 3 is a plan view.

Like numerals of reference indicate like parts in all the figures of thedrawings.

In the application of my present invention I employ an ordinary glassjar 5, of the type commonly known as a Mason fruit-jar, the upper partof which is provided with a neck 6 having a thread thereon, as is usual.

Adapted to be threaded on the neck of the fruit-jar is a metal cap 7comprising a ring 7 with a thread corresponding with the thread on saidneck, and an inwardly-projecting flange 7 at the upper end of said ring,thereby leaving an opening through the upper part of said cap. The rink7 of this screw-cap is provided with a number of holes, 8, which arelocated'at the base of the thread and are slightly spaced apart, as bestSpecification of Letters Patent.

shown in Fig. l. The particular function of these holes will bespecified hereinafter.

Between the screw-cap 7 and the upper edge of the mouth of the jar islocated a disk 5), composed of celluloid and preferably transparent, andbetween this celluloid disk and the jar I may, and preferably do, employa gasket 10 composed of oiled fiber. In some instances the gasket may bedispensed with, but in use I find that the employment of said gasket inconnection with the celluloid disk provides a tighter seal. Thecelluloid disk closes the opening in the screw-cap, and beingtransparent the upper part of the contents of the jar can be seenthrough said disk. This disk, being of celluloid, is also yielding andwill overcome the usual vacuuni which forms above the contents when theycool, and will also bulge outward in the event of formation of gas andbreak thus saving the ar.

By providing the screw-cap or flanged binding-ring wlth holes throughthe same, as shown, an effective gripping means is provided permittingsaid cap or ring to be more conveniently turned. Furthermore, the holesserve to reduce the weight of the screw-cap, and being disposed in themanner illustrated in the drawings also make the threaded portion of thering more yielding so that it will better bind upon the thread of theneck of the jar. Furthermore, any fluid which may overflow while thescrewcap is being applied will be wiped from the thread on the jarthrough the holes by means of the cloth usually employed in applyingsaid cap.

As will be readily seen, therefore, I pro vide a construction of fruitjar which is simple and cheap in construction, and effectwe in use.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent, is

1. A fruit-j ar having a threaded neck portion, a screw-cap adapted toengage the thread on the neck and provided with holes through thethreaded portion thereof, and a sealing device between the screw-cap andthe mouth of the jar, substantially as shown and for the purpose setforth.

2. A fruit-j ar having a threaded neck portion, a flanged screw-ringadapted to engage the thread 011 the neck and provided I name to thisspecification in the presence of w1th holes through the threaded pol-hontwo subscnblng wltnesses. theleof, a d L cellulpld dlslebetwee the HENRYB BURNS flange of the screw-13mg and the mouth 01 the ar, substantlallyas shown and for the Wvltnessesz purposes set fort-h.
